The primary object of my present inven tion is the provision of an improved mixer through which vapor or steam is supplied to tlie'explosive mixture as it passes from the carburetor to the intake manifold of theengine. V J

in this connectiom'my invention comprehends a mixing: device adapted to he. inserted between a? carburetor and intake manifold and adapted for connection with ing bores 'liy ineans'of which bolts 15 may he applied to secure it in place, metallic gaskets or packing "rings hei'n g usually, interposed between. its faces 'aiid the tlanges of the manifold and carlmreter, y Th i's ho(ly member is provided (in tially Wijtliaigas opening or passage 16 sul'istafhtially {equal in diameter the internal diameter of the outlet passage of thcQ-fcarhuyeter and the intake passage of ,tliQjllti IllfOh Langhs'o-d 'sposed with res; c t to it, receiving;

In order to thoroughly mix the explosive mixture supplied ing formed in from the carbureter with th'e steam supplied from the chamber. 18, I provide a screen 25 of any suitable foraminous material, preferably fine wire gauze, which screen is generally reinforced peripherally by a metallic ring 26, the peripheral edge of the screen and ring seatin against the shoulder 17, as best shown. in ig. 2.

A pipe 27 leads from the inlet port of the cut-off cock 21 to a vaporizing cup 29 which is connected'by a pipe 30to the cooling the cup to the engine, the small amount of water contained therein will be heated to generate steam or vapor which may be drawn 011' to the mixer and so to the engine cylinders.

In operation, the cut-off cock 21 is opened many suitable extent dependent upon the amount of steam which the operator desires to supply to the engine manifold and the engine is then driven in the usual manner. The steam drawn from the vaporizing cup passes into the chamber 18 of the mixer and from this chamber through the perforated pipes or tubes 23 into the gas passage 16 valves.

and so, together with the explosive mixture from the carbureter, through the screen 25 to the manifold 14 and from the manifold to the engine cylinders.

I By providing means for adding and thoroughly mixing the steam with explosive mixture from the carburete'r, I revent the formation of carbon in the m0 r and upon the spark plugs and also increase the life of lubricating oil used in the cylinders and As a result, the motor is smoother running and more powerful than would 'otherwise be the ease.

Havin thus described the invention, what is claim as new is:

1. A moisture supplying device and mixer adapted to be inserted between a carbureter and intake manifold and including a body having a fuel passage and an annular chamber surrounding the passage, a ring fitting in the passage and forming a wall for the chamber, perforated tubes extending across the ring and communicating at their ends with the chamber, and a mixing screen ber surrounding the passage, perforatedtubes extending across the passage and communicating at their ends with the chamber, and means providing for passage of moisture to the chamber.

3. A moisture supplying device and mixer adapted to be inserted between a carbureter and intake manifold and including a body formed with a fuel passage, a screen extending across the outlet end of the passage, perforated tubes extending across the passage between the inlet end thereof and the screen, and means for supplying moisture to the tubes.

4. A moisture supplying device and mixer adapted-to be inserted between a carbureter and intake manifold and including a body having a fuel passage and an annular chamber surrounding the passage, a tube extending across the passage and communicating at its ends with the chamber, said tube having perforations formed in that side directed toward the outlet end of the passage, and means for supplying moisture to the chamber.

5. A moisture supplying device and mixer In testimony whereof, I afiix my signa-.
